仅显示 Highcharter 中的组

Display only groups in Highcharter

我正在使用类似于以下代码的代码来分组显示条形图:

library(purrr) # map function to make grouped categories argument
library(dplyr) # for select function 

data(mpg, package = "ggplot2")

mpgg <- mpg %>% 
  filter(class %in% c("suv", "compact", "midsize")) %>% 
  group_by(class, manufacturer) %>% 
  summarize(count = n())

categories_grouped <- mpgg %>% 
  group_by(name = class) %>% 
  do(categories = .$manufacturer) %>% 
  list_parse()

highchart() %>% 
  hc_xAxis(categories = categories_grouped) %>% 
  hc_add_series(data = mpgg, type = "bar", hcaes(y = count, color = manufacturer),
                showInLegend = FALSE)

我得到以下图表:

Highchart Group Categories Wise

由于错位,我只想显示没有类别的组。我尝试了几种解决方案,但总是存在对齐问题。

有什么解决办法吗?

如果您不需要两组类别,您可以只定义没有分组的标准类别-categories.js 模块,就像这个 JS 示例:jsfiddle.net/BlackLabel/29kgtp3u
